QUARTZ-CRUSHER.

SPECIFICATION forming part 0f Letters Patent No. 480,647, dated August 9, 1892.

Application iiled September 8, 1891. Serial No. 405,132. (No model.)

T0 a/ZZ whom it may concern:

Be it known that I, ANDEREAs PHERsoN ANDERSON, a citizen ot the United States, residing at Oriental, Esmeralda lcounty, State of Nevada, have invented an Improvement in Quartz-Crushers; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to an improved appa ratus for pulverizing quartz and other rock; and my invention consists of the constructions and combinations of devices which I shall hereinafter fully describe and claim.

Figure l is a front elevation of my crusher, the pulp-bonnet being partially removed. Fig. 2 is a vertical cross-section 'of the same.

A A are two rollers journaled upon the supporting-frame B, of any suitable construction, so as to stand parallel with each other and near together. Upon these rollers and supported between them is a short cylinder O, the length of which is approximately the same as its diameter. Upon each end of the exterior of this cylinder are anges D, which serve as guides traveling against the ends of the rollers A to keep the cylinder in place upon the rollers. A belt E passes around this cylinder and any suitable driving pulley or device, from which power is applied to rotate the cylinder. 'l

The roller A, which is nearest the source of power, has its central portion a cut away sufficiently to allow the lower portion of the belt to pass out freely between the two sides of the roller, and the rear roller has a channel or depression c cut in its face corresponding with the channel in the front roller, so as to allow the belt to pass freely between the roller and the drum. By this means the drum is caused to rotate as rapidly as may be desired by the movement of the belt which passes about it, and the supporting-rollers turn freely, so as to allow it to rotate easily. The druln is made of iron or other suitable material, and has in the center, projecting inwardly, a ring or flange G, which serves to divide its interior into two parts. Within this'drum are fixed the dies I-l, which. are made in the form of rings, the central portion of which is thicker than the ends. The inner ends of the rings abut against the central ring and the outer ends against a ring I, which extends entirely around the inside of the drum at each end, said rings being separate from the cylinder O and fitted into its ends against the ends of the dies H in any appropriate manner. The thicker portion of these dies form the surface upon which` the Crusher-rollers F travel.

- This Crusher consists of two separate rollers, one of which is adapted to travel in each of the compartments formed by the central ring G of the cylinder. These rollers have'square tapering holes through their centers and are connected together by a square shaft f, (which is also slightly tapering,) which is screwed fast in place by a nut f', fitting onto the screw-threaded smaller end of the shaft and seated in the depression made for it in that end of the roller. Around each of these rollers is fitted a shoe Q, which consists of a cylindrical drum open at one end and having a head at the other. These drums fit over the ycylindrical rollers, being put on from the inside, so that the closed ends or heads are adjacent to each other.

Square holes are made through the inner ends of the shoes to lit over the shaft and a square sleeve q fits the vshaft between the two rollers, this sleeve abutting against the ends of the shoes, and thus holding them to their place on the cylinders. By this construction it will be seen that the dies within the cylin-l der and the shoes upon the rollers maybe removed and replaced at any time without much difficulty.

At each end of the cylinder is tted a screen K. The peripheries of these screens abut against the flanges D upon the outer ends of the drum and are clamped in place by rings L, which fit outside of the screens and hold them against these flanges, being secured by suitable bolts l.

M is a bar bolted or otherwise secured to the rings L and extending across the end of the cylinder, having an enlargement at the IOO between the periphery of thescreen andthe inner ends of the dies within the cylinder,.as previously stated.

A feed-pipe O extends from the supplyhopper down to a point above the cylinder,

where it divides, and one branch passing` around each end" of the cylinder delivers the" material through the central feed-funnel N.

When the apparatus is set in urotioiig,the5 drum or cylinder is rotated with great rapidity and the two-part roller is caused to travel around itsl interior, while-the material? tab@ crushed is fed in through the feed-hopper and chutes. it escapes through the screens and is discharged over` ama1gamatingplatcsorin any usuali er desired man-ner;

Giver' eachf end et ,the cylinder are.: iittedl. what Il term` pulpfhonlnets l?, which are slightly tunaelshapedn and serve" te prevent thiepul' fromf being' splashed out to* w great'i distance iroml-the` cylinder by ifte-v rapid rot tion.
